The Materials Project

CeOCdAs is Parent of FeAs superconductors structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ce3+ is bonded in a 4-coordinate geometry to four equivalent As3- and four equivalent O2- atoms. All Ce–As bond lengths are 3.34 Å. All Ce–O bond lengths are 2.38 Å. Cd2+ is bonded to four equivalent As3- atoms to form a mixture of distorted edge and corner-sharing CdAs4 tetrahedra. All Cd–As bond lengths are 2.81 Å. As3- is bonded in a 8-coordinate geometry to four equivalent Ce3+ and four equivalent Cd2+ atoms. O2- is bonded to four equivalent Ce3+ atoms to form a mixture of edge and corner-sharing OCe4 tetrahedra.
